An interval of up to 45 weeks between the first and second dose of the AstraZeneca vaccine led to an enhanced immune response, rather than compromising immunity, the study said.
"This should come as reassuring news to countries with lower supplies of the vaccine, who may be concerned about delays in providing second doses to their populations," said lead investigator of the Oxford trial, Andrew Pollard.The researchers said the results for a delayed AstraZeneca third dose were positive, particularly as nations with advanced vaccination programs consider whether third booster shots will be required to prolong immunity.
She explained the research showed the AstraZeneca jab "is well tolerated and significantly boosts the antibody response." The development of the jab, which is being administered in 160 countries, has been hailed as a milestone in efforts against the pandemic because of its relatively low cost and ease of transportation.
